How can one combine missed prayers with current prayers, and what is the number of rak'ahs for each, and is it more correct for a resident to offer the missed prayer or the current prayer first?

Whoever misses a prayer, whether with an excuse or without one, must make it up (qaḍāʾ). It is prayed in the same manner as it would be performed on time (adāʾ), except for Jumuʿah (Friday prayer), which is made up as ẓuhr (noon prayer). If there are many prayers to be made up, they should be prayed in order, one after another. If they coincide with the current prayer, the missed prayer takes precedence, unless there is a fear that the time for the current prayer will expire. If the make-up prayer is performed while resident (not traveling), the prayer is complete, regardless of whether it was missed while resident or traveling.
